Deep learning has come a long way since the days when it could only recognize handwritten characters on checks and envelopes. Today, deep neural networks have become a key component of many computer vision applications, from photo and video editors to medical software and self-driving cars.

Roughly fashioned after the structure of the brain, neural networks have come closer to seeing the world as humans do. But they still have a long way to go, and they make mistakes in situations where humans would never err.

These situations, generally known as adversarial examples, change the behavior of an AI model in befuddling ways. Adversarial machine learning is one of the greatest challenges of current artificial intelligence systems. They can lead to machine learning models failing in unpredictable ways or becoming vulnerable to cyberattacks.

Their quantum phase battery consists of an n-doped InAs nanowire forming the core of the battery (the pile) and Al superconducting leads as poles. It is charged by applying an external magnetic field, which then can be switched off.

Cristina Sanz-Fernández and Claudio Guarcello, also from CFM, adapted the theory to simulate the experimental findings.

The battery is being further developed and improved at CFM premises in a collaboration between the Nanophysics Lab and the Mesoscopic Physics Group. These advances could contribute to enormous advances that many say will come from the field of quantum computing.

Ebikes may indeed require less pedalling effort than regular bicycles, but most still offer little in the way of cargo capacity or protection from the elements. The CityQ is designed to provide both, along with four-wheeled stability.

Created by Norwegian company CityQ AS, the vehicle is pedalled like a bike, with a 250-watt motor augmenting the rider’s pedalling power. However, the pedals aren’t directly linked to the drivetrain. Instead, the CityQ features what is simply described as “a software-managed drivetrain – like you find in electric cars.”

We’re still waiting to hear back about what that entails, although we suspect it may be something like the setup utilized in the Mando Footloose ebike – it uses an alternator to convert the rider’s pedalling power into electricity, which is stored in a battery that powers the motor.

Scientists have figured out a cheaper, more efficient way to conduct a chemical reaction at the heart of many biological processes, which may lead to better ways to create biofuels from plants.

Scientists around the world have been trying for years to create biofuels and other bioproducts more cheaply; this study, published today in the journal Scientific Reports, suggests that it is possible to do so.

“The process of converting sugar to alcohol has to be very efficient if you want to have the end product be competitive with ,” said Venkat Gopalan, a senior author on the paper and professor of chemistry and biochemistry at The Ohio State University. “The process of how to do that is well-established, but the cost makes it not competitive, even with significant government subsidies. This new development is likely to help lower the cost.”
